GetVarPointDV

Fills the array with the information about points that are closest to the received point.

Syntax

IppStatus ippsGetVarPointDV_16sc(const Ipp16sc* pSrc, Ipp16sc* pDst, Ipp16sc* pVariantPoint, const Ipp8u* pLabel, int state);

Parameters

pSrc

Pointer to the reference point in format 9:7

pDst

Pointer to the closest to the reference point left and bottom complex point in format 9:7

pVariantPoint

Pointer to the array where the point information is stored

pLabel

Pointer to the table that stores the labels.

state

Number of states of a convolution coder.

Description

The function ippsGetVarPointDV is declared in the ipps.h file. This function fills the specified array pVariantPoint with the information about 2D complex points that are closest to the reference point pSrc. This information includes the corresponding labels from the offset table and calculated errors. The number of possible states may be 16, 32, and 64. The number of points in the array depends on the number of states: if state = 16 , then 4 points will be referenced in the array, if state =32 or 64, then 8 points will be referenced.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when any of the specified pointers is NULL.
